Eurostar services have been decimated during the pandemic with just two services now running each day.
Manuel Cortes, general secretary of the TSSA union said the Government must “pull out all the stops” to save Eurostar following a meeting with treasury officials that aimed to prevent the collapse of the channel tunnel train operator.
Transport secretary Grant Shapps recently told the transport select committee the government had no plans to bail out Eurostar because the company is majority owned by the French state.
Mr Cortes said: “The focus now must be on recovery and we will do everything we can to ensure that Eurostar has a bright future. Ministers must pull out all the stops and work with us in this urgent task to safeguard Britain’s green gateway to Europe.
“Eurostar remains in a perilous situation but is far too important to fail. I know the company, and all our brilliant members, are ready to get back to a normal service as soon as it is safe to do so. The Treasury should make every effort to ensure that happens. No ifs, no buts.”
